HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 266,838, dated October31, 1882,

Application filed December 14, 1881.

To all whom it may concern Be it known that I, CHARLES KEIGHLEY, asubject of the Queen of Great Britain and he land, and a resident ofVineland, Cumberland county, New Jersey, have invented certainImprovements in Heel-Burnishing Machines, of which the following is aspecification.

My invention relates to certain improvements in the well-known Tapleyheel-burnishing machine, the object of my invention being to dispensewith the necessity of employing an attendant for each machinean objectwhich I attain by performing automatically a duty, which, in the machineas at present constructed, demands the continual attention of the personin charge.

In the accompanying drawings, Figure 1 is a side view, partly insection, of a Tapley heelburnishing machine with my improvements; andFig. 2, a sectional plan on the line 1 2.

A is the main column or standard of the machine, on the top of which areformed bearings for the rock-shaft B, which is furnished with acounterbalanced arm, D, and to the outer end of the latter is pivotedthe burnishing-tool 0c. The vibrating movement is imparted to therock-shaft by means of the usual segmental rack and pinion, thesegmental rack being formed on one arm of a lever, E, the other arm ofwhich is connected by a rod, a, to a crankpin on a disk, I), secured tothe driving-shaft F, the latter being furnished with the usual fastpulley and loose pulley, and being adapted to hearings in a frame, G,projecting from the rear of the standard A. As the rock-shaft vibratesthe burnishing-tool is caused to traverse back and forth around the heelof ashoe, y, which is clamped in a frame, J, the latter being guided bya slotted segmental arm, d, on the standard, and being secured to theupper end of a rod, 0, the lower end of which passes through a pivotedbox and is acted upon by a set-screw, so as to raise or lower the rod 0and bring the heel of the shoe into proper relation to theburnishing-tool. All of these parts are common to the machine as nowconstructed, and in operating such a machine it is necessary to impart amovement in the direction ofthe arrows to the frame J, carrying theshoe, in order that the heel may be caused to traverse longitudinallybeneath the burnishing-tool while the latter moves around said (Nomodel.)

heel. Thisdutyis performed by the attendant, who presses his shoulderagainst the head fof a spring-rod connected to one of the clam pingjawsofthe frame, one of the arms of the latter being grasped by the hand, sothat the necessary forward-and-back ward movement can be imparted tosaid frame. This method of operation necessarily requires an attendantfor each machine, and, in order to avoid this necessity, 1 cause thelongitudinal movement to be imparted to the frame J automatically, sothatthedutyoftheattendantisconfined simply to applying shoes to andremoving them from the clamping-frame J, whereby one attendant isenabled to take charge of a number of machines. In the present instancethe frame J has a projecting pm, i, to which is adapted the hooked outerend of a link, h, which passes through a slot in the standard A, and isconnected at its inner end to one arm of a lever, M, contained withinthe standard, the other arm of said lever being connected to a rod, m,which is adapted to slide in hearings in the lower portion of thestandard, and is connected by a link, a, to a crank-pimp, on aworm-wheel, q, the latter receiving motion from a worm, It, on a shaft,j, which is adapted to bearings in the frame G, and is driven from themain shaft F through the medium of a belt and pulleys, or equivalentdevices.

It will thus be seen that when the machine is in operation a slow orcomparatively-slow reciprocating movementof the frame Jis effected, soas to properly present all parts of the heel for the action of theburnishing-tool.

In order to vary the extent of movement of the frame J, I slot the leverM for the reception of the fulcrum-pin 10, the latter being carried by abracket, 8, which is adjustable vertically on the standard A, aclamping-bolt t, passing through a slot, at, in said standard, and beingfurnished with a handle, a, so as to readily secure the bracket in anyposition, to which it may be adjusted. By the vertical adjustment of thefulcrum-pin of the lever the relative length of the arms of the lattermay be varied and the extent of movement of the frame J increased ordiminished, as required, the movement of the rod at being uniform.

When it is desired to draw the frame J outward, in order to apply a shoethereto or remove one therefrom, the said frame is released vised withinthe scope of my invention.

from the control of the link It by elevating the hooked end of thelatter, so as to free the pin 2'. A lever, g, provides a means ofreadily aocomplishing this result.

Various modifications of the mechanism for transmitting motion to theframeJ may be de- For instance, the link It might be connected directlyto a crank-pin on a wheel driven from the shaft F, the crank-pin beingadjustable, so as to vary the lengthof stroke; or the frame J might insome cases be stationary, the longitudinal movement being imparted tothe bur nishing-tool, the result being the same in both cascsnamely, thetraversing of the burnisher over all parts of the heel without thenecessity of any attention on the part of the operator. The arrangementshown is preferred, however, as it can be applied to the machines as nowmade without any material alteration or rearrangement of the parts ofsaid machines.

I claim as my inventiona l. Thecombination,in aheel-bnrnishingmachine,of avibratingshaft carrying aburnisher, a shoe-carrying frame, adriving-shaft, and

mechanism, substantially as described, whereby said driving-shaftimparts to the frame or burnishera definite reciprocating movement inadirection at right angles to the plane of vibration of theburnisher-shaft, as set forth.

2. The combination of, the standard A, the vibrating burnisher, theshoe-carrying frame J, adapted to move in a plane at right angles to theplane of movement of the bnrnisher, the lever M, connected to the saidframe J, and mechanism for vibrating said lever, all substantially asspecified.

3. The combination of the slotted standard A, the vibrating burnisher,the shoe-carrying frame, the link h, the lever M, theverticallyadjustable bracket 8, carrying the fulcrum-pin w, and meansfor clamping the bracket to the standard, as set forth.

4. The combination of the standard, the vibrating burnisher, theshoe-carrying frame,

the lever M, the link It, the guided rod m, and I the worm-wheel andworm for actuating the latter, as specified.

in testimony whereofIhave signed my name to this specification in thepresence of two subscribing witnesses.
